IPC: G01F1/68
Filed: 1993-04-30
Abstract: Thermal flow sensor (I) comprises (a) a heat sensitive, electrical resistance (3) having an electrically insulating base, a heat sensitive resistance element (32) arranged on a holder and comprising a resistor that changes with temp. corresp. to a predetermined temp. coefft.; (b) a holder to hold the base inside a flow of a fluid; (c) a bridge circuit having a heat sensitive resistance and several other resistances; and (d) a control switch to control the bridge circuit so that the bridge circuit maintains a predetermined equilibrium state, and to establish the flow of fluid from the equilibrium. The heat sensitive resistance element has a heat sensitive main section of 1st resistance temp. coefft., and a thermal buffer section of 2nd resistance temp. larger than that of the 1st. The thermal buffer section is arranged near to the holder. The heat sensitive electrical resistance is also claimed.

Patent DE-4321966-A1 (DE)
Inventor: HALM HANS
IPC: B43M11/00
Filed: 1993-07-01
Abstract: The invention relates to a novel method of producing an adhesive stick which has a rotatable foot part with a rotary spindle, said spindle engaging in a holding device for the stick substance (piston, cup, anchoring plate) and the holding device being fitted into a sleeve which surrounds the stick substance. By means of the rotary spindle, the stick-shaped adhesive substance can be moved upwards and downwards. According to the invention, the sleeve (2), together with the piston (1), forms a one-part injection moulding which is connected to the sleeve wall via intended tearing points (3). For assembly, the foot part with the rotary spindle is pushed through a cutout arranged centrally in the piston until the upper part of the foot part strikes against the lower edge of the sleeve, the stick substance is then poured into the unit thus formed from the sleeve, piston and foot part with the rotary spindle and, after completing the filling operation, the rotatable foot part is actuated and the piston is thus raised into the intended end position (10) whilst tearing off the intended tearing points. The invention also relates to an arrangement for carrying out the method, consisting of   a) a rotatable foot part (7), a rotary element (7B) and a rotary spindle (7A), the foot part having two supporting plates (9A, 9B), and b) a one-part injection moulding comprising a sleeve part (2) which is open at both ends and a piston (1) with intended tearing points (3).   <IMAGE>

Title: Position detection device for moving body - has stroke compensation mechanism between operating push rod and slider acting as screen for inductive or capacitive proximity switch
Inventor: ARTES PATRICK
IPC: H03K17/95
Filed: 1993-08-02
Abstract: The device has a mechanical detection head with a movable push rod (2) operated by the moving body and cooperating with a sensor (3) providing a position detection signal. The sensor is provided by a proximity switch with a movable slider (42) acting as a screen for the sensor, operated by the push rod. A piston (43) and a pair of cooperating coil springs (44,45) act as a compensation mechanism for the difference in stroke of the push rod and the slider. The movement of the latter is limited by a stop edge (411) provided by a sleeve (41) which is fitted to the sensor, made of a non-magnetic material. USE/ADVANTAGE - Allows substitution of mechanical contact switch by proximity switch without adjustment or change of housing or detection head. Reliable device for providing electrical output signal when moving body is in specific position.

Title: Fuel system for an internal combustion engine with an adsorber for fuel vapours
Inventor: FISCHER HANS-UDO
IPC: F02M25/08
Filed: 1994-02-24
Abstract: A fuel system for an internal combustion engine (1) contains a fuel tank (2) with a vapour space (4) situated above the fuel level (3), which space can be connected by a slide valve (5) to a line (6) leading to the intake system of the engine (1) and to an adsorber (8) in the nature of an activated charcoal filter. This connection is made only in the event of excess pressure in the vapour space (4) or in the event of a negative pressure which stems from temperature-dependent volume contractions in the fuel tank (2). The slide valve (5), on the other hand, prevents the transmission of the negative pressure in the intake pipe of the engine (1) during operation of the latter, so that additional vapour formation in the tank (2) is avoided. <IMAGE>

Patent DE-4408924-A1 (DE)
Inventor: KOLZAREK FRANK
IPC: C21D1/673
Filed: 1994-03-16
Abstract: A process and device are disclosed for influencing the changes in size and shape of workpieces during hardening. Mechanical accessories, in particular mandrel fixtures, are used for hardening workpieces. In known processes, the carburised workpieces are set on said mandrel fixtures and quenched. In order to simplify and reduce the cost of a hardening process by means of mandrel fixtures, the individual operations such as carburising, stacking of workpieces on the mandrel fixture and quenching are combined in a single process. A mechanical accessory used to carry out this process is made of a material that does not carburise together with the workpieces, i.e. the surface of the mandrel fixture is not changed into a hardened microstructure during carburising.

Title: Raster=type sub=ceiling slab
Inventor: KNAUF JEAN ALFONS
IPC: E04B9/00
Filed: 1994-06-15
Abstract: A closed top plate (8) made of low melting point material rests on supports (11) at a distance from the baseplate (7) so their interval (10) remains open to the top. The supports are set directly between the two plates, notably at the corners of the cover plate (6) so the supporting part (12) connects to a centralising part (13) arranged clear of the top plate edge. Top and baseplates are made of gypsum or the baseplate comprises perforated sheet frame whose edge is drawn up all round so its horizontal flange bears on the side flanges of the support lattice. In this case, the supports are arranged between top plate and the bottom of the baseplate. The top strip of the top plate is spaced from the edge flange of the baseplate by as much as the interval between the two plates. The supports (11) can be made of fusible plastics or paraffin for preference. Thus in fires the supports melt so the top plate descends onto the baseplate to close off the baseplate holes (9) as shown.
